The father was booked into Parish Prison on a count of principal to second-degree murder.

Baton Rouge police originally booked both Lobranos on one count of attempted second-degree murder in the beating of Lionell Trumble, 60, police said.

The elder Lobrano was arrested at the scene Jan. 5 and his son was arrested a few days later, Kelly said.

Trumble, who had been hospitalized since the beating, died March 12 from his injuries, police have said.

Baton Rouge police said March 20 that they were looking for the Lobranos, who were out on bail, to re-arrest them on the upgraded counts.

Trumble, 890 N. 39th St., was severely beaten with a board when he intervened in a fight between his sister and her ex-boyfriend, the elder Lobrano, at 3864 Ozark St., police have said.

A witness told police that the younger Lobrano hit Trumble over the head with a wooden board, knocked him down and continued to hit him and stomp on him, an arrest warrant for the younger Lobrano says.

Trumble was in a coma at a hospital, and doctors said he had multiple facial fractures and bleeding in the brain, the warrant says.
